Karl Leonhard Reinhold (1757–1823) became a leading interpreter of Immanuel Kant’s Critique of Pure Reason. He authored the influential Briefe über die Kantische Philosophie, clarifying transcendental philosophy. Reinhold held academic posts in Jena and Vienna, lecturing on metaphysics and aesthetics. He developed the Elementary Philosophy, a systematic framework for Kantian ideas. His writings sparked debates across European universities and shaped early German Idealism. Reinhold’s efforts cemented Kant’s legacy and influenced subsequent thinkers like Fichte.

Often called the grandfather of personal success literature, Hill pioneered the self-help genre in the early 20th century. He studied the habits of the most successful individuals, including Andrew Carnegie, to formulate principles of achievement. Originally published in 1937, Think and Grow Rich remains one of the bestselling books of all time with over 100 million copies sold. Hill’s philosophy emphasizes the power of desire, belief, and perseverance in attaining personal and financial goals. His influential work continues to inspire entrepreneurs, leaders, and readers worldwide.
